I recommend to take a look at oscilloscope / - graph images  from "square" 
waves out of different types of sources -i.e. digital and analog (synths and 
other generator types/sources).

By theory, any square wave could be constructed by a infinite number of 
(sinus) signals, while many of that images seems like produced from a finite 
number of such "signal parts". this means - if i think correctly - a really 
perfect square would have "infinite energy" required (pls correct me, if i'm 
wrong here).

A lot of the "subtile timbre" of a synths square wave could be "found" in the 
(by tech limits / physics always a bit imperfect) "edges" of the squares. i 
assume if you want to reproduce such "analogish" square in digital, the 
resulution of the sampling and reproduction at this stage should be 

sorry for possible tech imperfections -my view onto this is more one from a 
synth user then a DSP specialist.
